Portable oxygen concentrators require maintenance and service to ensure they operate correctly. Regular maintenance of your Inogen One G3 will keep the unit performing at the highest level and will extend the life of the unit.

By following these basic maintenance tips, you can rest assured that your Inogen G3 will last for years to come.

Here at American Medical Sales and Rentals we know that once you’ve been prescribed oxygen therapy things can get a little overwhelming. There’s a lot of information to learn and a lot of equipment and products to consider. Luckily, here at the Oxygen Concentrator Store by American Medical we’re well versed, being an industry leader since 2001.

We are headquartered in Centennial, CO and support our oxygen customers in the USA and around the globe.
